We designed a suction attachment for the radiosurgical treatment of intraocular malignancies with the Leksell gamma unit (Gamma Knife). Our device consists of a circular suction chamber and an adjustable unit to be fixed to the Leksell stereotactic head frame. All components are made of plastic materials in order to avoid artifacts in CT or MRT imaging. A permanent suction of 600-800 mbar is provided by a standard vacuum pump, powered by a portable battery. Suction times up to 40 min were well tolerated in all cases. We successfully used this device, performing 17 radiosurgical treatments in 8 patients with large or extra-large uveal melanomas and one patient suffering from a choroidal metastasis.
我们设计了一种用于使用Leksell伽玛刀（伽玛刀）对眼内恶性肿瘤进行放射外科治疗的吸引附件。我们的装置由一个圆形吸引腔和一个可调节单元组成，可固定在Leksell立体定向头架上。所有部件均由塑料材料制成，以避免在CT或MRT成像中产生伪影。由便携式电池供电的标准真空泵提供600 - 800毫巴的恒定吸力。在所有情况下，长达40分钟的吸引时间耐受性良好。我们成功地使用了该装置，为8例患有大或超大脉络膜黑色素瘤的患者以及1例患有脉络膜转移瘤的患者进行了17次放射外科治疗。
